In a search for new cerebral protective agents, a series of 4-(3- or 4-nitrophenyl)-6-phenylpyridines (or pyridazines) and 2-(3-nitrophenyl)-6-phenylpyridines, possessing an amino moiety at the C-3 position of the pyridine(or pyridazine) ring, were synthesized through the corresponding novel 1, 4-dihydro derivatives and tested for anti-anoxic (AA) activity in mice. Four compounds (2c, 2f, 3a, 4a) possessed significant AA activity at a dose of 32 mg/kg, i.p. These results suggest that four-atom linkages between the C-3 position of the pyridine (or pyridazine)ring and the nitrogeneous basic moiety also seems to be a prerequisite for the expression of AA activity.
在寻找新的脑保护剂的过程中,合成了一系列具有氨基基团在吡啶(或吡嗪)环C-3位的4-(3或4-硝基苯基)-6-苯基吡啶(或吡嗪)和2-(3-硝基苯基)-6-苯基吡啶,通过相应的新型1,4-二氢衍生物合成,并在小鼠中测试其抗缺氧(AA)活性。四种化合物(2c、2f、3a、4a)在32 mg/kg的腹腔注射剂量下表现出显著的AA活性。这些结果表明,吡啶(或吡嗪)环C-3位与含氮碱性基团之间的四原子连接似乎也是表达AA活性的先决条件。
